The SIPROTEC 7SA61 distance protection relay provides universal protection, control and automation for electrical systems. Implement this flexible relay across all voltage levels to secure your infrastructure.
Deliver reliable and selective protection for your electrical network. This relay prevents non-selective tripping with its current transformer saturation detector for system stability. Achieve high-speed fault clearance and precise protection for even short lines.
High-speed tripping times that enhance system stability and reduce downtime. Digital relay-to-relay communication improves selectivity and availability for optimized fault isolation.
This product is currently being phased out. Contact your Siemens representative for details.
Enable continuous operation and minimize downtime. Protect your assets with reliable functions from high resistance earth-faults and over/undervoltage events for system integrity.
Streamline operations with integrated control and automation. Reduce operating costs through efficient fault management and adaptive auto-reclosure for long-term savings.
Deploy a universal relay for all voltage levels. Adapt your flexible system to evolving operational needs to maintain an effective, relevant protection solution over time.
Achieve high-speed tripping for rapid fault clearance. Use an impedance setting range with small settings for precise protection of the shortest lines. Prevent non-selective tripping with a current transformer saturation detector.
Control circuit breakers and isolators with integrated command functions. Employ digital relay-to-relay communication for robust data exchange.
Detect power swing frequencies up to 7 Hz with self-setting capabilities. Implement non-switched distance protection with 6 measuring systems. Protect against high resistance earth-faults for single and three-phase tripping.
